On adding Firebase Auth as a separate module in compose multi platform app, was not able to build the app for iOS, but was able to do so in Android

@dinesh-thiyagarajan how did you solve this? I just ran into same error

[dinesh-thiyagarajan]

Hi @timhuang1018 Open the iosApp (which is under the root directory) folder in xcode.

1. Click on File -> Add package Dependencies. In the search option search for https://github.com/firebase/firebase-ios-sdk and select firebase-ios-sdk and click on add package
2. Come back to android studio

`import SwiftUI import Firebase

class AppDelegate: NSObject, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool { FirebaseApp.configure()

    return true
}

}

@main struct iOSApp: App {

@UIApplicationDelegateAdaptor(AppDelegate.self) var delegate

var body: some Scene {
    WindowGroup {
        ContentView()
    }
}

}`

Paste the above code in iOSApp.swift file (not able to render the code here properly, but copy paste the code it should work fine), here we are initializing the firebase. also make sure you have added the GoogleService-Info.plist file inside the root/iosApp/iosApp/GoogleService-Info.plist
